UNITED sTATEs PATENT OFFICE. WILLIAM W. DU NBAR, OF ALAMO MII NG DISTR', ARIZONA TERRI'I'ORY, ASSIGITOR OF ONE-HLF TO A. P. MAGINNIS, OF LOS ANGELES, CALIFORNIA.

REFRIGERATOR.

'l Speciflcation of Letters Patent. Ptnted Nov, 22', 1910,

Application' filed July 25, 1910. Serial No. 573,600.

To all who'm it 'may conce'r'n;

Be it known that I, WILLIAM W. DUNBAR,` a citizen of the United States, residing at Alamo Mining District, Yunia county, Arizona Territory, have invented a new and useful Refrigerator, of whichthe following is a specification.

My object is to make a refrigerator by' providing means for producing an air draft; and my invention. consists of the novel features herein shown, described and' claimed.

In the drawings; Figure 1 is a perspective view of a refrigerator embodying the rinciples of my invention. Fig. 2 is a orizontal section on the line 2-2 of Fig. 3. Fi of li`igs. 1 and 2. Fig. 4 is an enlarged fragmental perspective detail showing the water circula-tion. Fi 5 is fragmental detail of the air inlet yas indicated by the arrow 5' in Fig. 3.

Referring to the drawing in detail, the outer casin A comprises the bottom' 1, the sides 2 and 3, the back 4, top 5, the top covers 6 and 7, and the front outside door 8. Air inlet openings 9 are formed in the back 4 and a sliding damper 10 regulates the passage of the air through the openings. The top 5 covers the front one-third of the casing. A flue 11 extends up'wardly from the top 5, and a damper 12 regulates the air passage from the casing u the flue.

The inside casing B is o sheet metal such as copper or zinc and-comprises the bottom 13, the sides 14 and 15,' the back 16, the top 17, the shelves 18, 19 and 20, and the doors 21, 22 and 28. The casing thus constructed is about three inches smaller all around than the outside casin The in the bottom of t e outsi e casing and legs 25 rest 'in the pan and support the inside casing.

A' door or partition 26 is hinged to the rear edge of the top 5 and swmgs down against the top of the inside casing, and doors or partitions 27 and 28'are hinged to the sides of the inside casing and swing outwardly against the sides -of the outside casing, said doors 27 and 28 being in a line with the door 26, so as to divide the air space around the inside casing into the down 0'. 3 is a Vertical section on` the lines 3-3.

anv 24 is' placed' draft chamber 30 and the' up-draft chamher 30. The doors or partitions 26,' 27 and 28 are hinged so as to facilitate moving the inside casing into or out of the outside casing, and so that they may be opened in cold weather to'stop the circulation. The doors or partitions 27 and 28 terminate a distance tically slitted, so as to form wicking to take the water out of the pan and carry it down against the outside of the pan thereby stiinulating evapo-ration and mcreasing the air draft. The fresh air passes inwardly ,through the openings 9 and i downwardly around the lower ends of the doors 27 and 28, and 'then upwardly and out of the flue.A

'The detailsmay be varied in manyways ,Without departing from the spirit of my invention;

I claim: 7

A refrigerator comprising lan outside casing; an inside casingmounted in the outside -casing, there being an air space between the casings; a partition in said air space, betwcen the top of the inside casing and the top of the outside casing; partitions extending downwardly from the ends of the first partition, between the sides of the inside .casing and the sides of the outside casing,

and terminating a distance above the bottoml of'the outside casing; so asto divide the air space vertically into two chambers, said chambers being connected at the bottom,and there being an air inlet on one side'of the partitions, and there being a flue outlet o n the other side of the partltionsz, a pan for water on the top of the inside casin back of the partitions; and a wicking eading from the pan downwardly outside of the' inside easing.
